Abstract
Systems and methods for regulating a switching converter are disclosed. One embodiment of the present invention relates to a power supply system that includes a switching converter that provides an output voltage by alternately turning on and off a high-side transistor and a low-side transistor both coupled to an output inductor through a switching node. The switching converter includes a drive circuit that regulates the output voltage based on a feedback signal. The power supply system also includes a simulated output generator that generates and provides the drive circuit with a simulated inductor waveform as the feedback signal based on a low-side output waveform of the low-side transistor measured at the switching node during off-times of the switching converter.
